How do I fix an abort(OOM) error

[debater-coder]

I'm trying to export a bunch of frames to a video using ffmpeg.wasm. Currently I write all the frames using ffmpeg.wasm and then I transcode them with this command:

 await ffmpeg.run(
    "-r",
    "30",
    "-f",
    "image2",
    "-s",
    "1920x1080",
    "-i",
    "frame-%03d.png",
    "-vcodec",
    "libx264",
    "-crf",
    "25",
    "-pix_fmt",
    "yuv420p",
    "-vframes",
    "120",
    "twisty.mp4",
  );

It works up to around frame 38, and then I get an abort(OOM) error. I've heard that compiling ffmpeg.wasm with ALLOW_MEMORY_GROWTH=1 fixes it, but I've checked the docs on compiling the core, and it says to invoke a script build_with_docker.sh but there is nothing that says how to pass these arguments to the script. I have no experience with Emscripten and the assumptions I've made here may be wrong.
